For a Process transfer function gcs 2e3s5s1 which one of the

For a Process transfer function gc(s)= (2e^(-3s))/(5s+1), which one of the following statement is NOT true:

a) Uncertainty in time constant Tp=3 will NOT affect the phi

b) Uncertainty in process gain kp=2 will affect the AR

c) Uncertainty in process gain kp=2 will NOT affect the phi

d) Uncertainty in time-delay theta = 3 will affect the phi

e) None of the others

Solution

Option a is correct

All the remaining options are True

Uncertainity in Time constant T_p=3 will NOT affect phi

Because while finding Phi it will definitly effects the phi
